well before you put your shrimp in, put in your livesand/deadsand first and if you have any uncured liverock you can put that in also
What i would do for the shrimp is to put it the shrimp in a media bag, those fine mesh bags for media, and put the shrimp in there, and put it in an area with circulation, becaues its VERY hard to clean shrimp chuncks that are floating around and obviously, no one wants to clean up dead shrimp pieces that have decayed all over you tank, 3-7 dollar bag will save you plenty of time and future backpains, trust me i had to clean this crap off my friends tank
it will take awhile before your sand turns live, if your using dead sand, seed it with live sand, id atleast use 30-50% livesand, i wouldnt run any wet/dry filters during the cycle, learn how to properly clean the bioballs, they can cause your nitrates to raise because of fishwaste trapped in the bioballs
good luck
